Great to hear that Greg - looking forward to seeing the results of the first light
I hope you don't mind - in another thread Nick has shared an interesting graph of 128 scopes from a Russian lab showing PV and RMS vs Strehl with some approaching Strehl of 1.
I approximately positioned the values from your certificate on the graph - blue line for PV and red for RMS - both are better than 128 scopes in this sample

Clearly, none of these scopes, with some approaching Strehl of 1, are better than PV 1/8 wavelength - maybe Russians got it wrong too
